EXHIBITOR Application tiled February To all 'whom it may concern.'

Be it known that l, GUY Dickinson, a citizen of the United States ci America,- and resident of Little Rock, in the county of Pulaski and State of Arkansas, have invented certain new and useful llmprovements in Exhibitors, of which the following is a specification. .1

This invention relates to exhibitors Jfor demonstrating effects attainable in masonry such as walls, mantle construction, and other objects where faced bricks are to be laid with raked joints, although the invention will also prove advantageous for demonstrating the eects of other masonry where the building material, such as the bricks, blocksfor the like, is of certain shades or colors and the mortar is of a contrasting or lin other words, -this invention provides means whereby' the building material such as the bricks may be' shown as associated with joints when the mortar of the joints is of diderent colors in order that by its use, selection can be made as to the material to be employed in the construction of a certain object. i

llt is an object of this invention furthermore to produce an exhibitor of the character indicated in which that part of the structure indicating the mortar will have a natural granular appearance in order that the mortar may be more realistically disj played.

llt is a further object of this invention to produce an exhibitor of the character indicated in) which the elements relied on to give color to the spaces at the joints between the courses of building material may be expeditiously changed, so that a demoustrator may employ successively a number of colored elements. y

With the foregoing and other objects in view, the invention consists inthe details of construction, and in the arrangement and combination ofoparts to be hereinafter morefully set 'forth and claimed.

lin describing the invention in detail, reference will be had to the accompanying drawings forming part of this application wherein like characters denote corresponding parts in the several views, and in which-f- O Figure 1 illustrates a view in elevation of an exhibitor embodying the invention;

Figure 2 illustratesa vertical sectionalview thereof.

ln these drawings, 5 denotes a suitable molding constituting the frame, and the said frame may beconstructed with a plurality of panels such as 6 and 7, it being understood that the number of panels may be changed to suit particular requirements.

The frame has a central channel-or space in which the colored elements 7 are located, and these colored elements are preferably in the nature of cards the surfaces ofwhich are dierently colored in order that their color may be exhibited through the openings of the trame or the panels, as will presently appear. 'llhe frame is provided with what may be termed backing strips or plates 8 preferably of translucent material such as celluloid, frosted glass or the like, although under certain conditions of use, transparent material might be used. However, the transparent material would not be as eflective in giving the granular appearance to the material at the joints of the building blocks or materialn lVhile heretofore the building material has been referred to in a general way, the in- Y vention is illustrated as being used to exhibit brick structures, the faces of the bricks being dierently ornamented to show the et- :tect of diderent types or designs, and in the further description the building material or blocks will be referred to as brlcks; it ybeing understood that the term may also embrace 1cielnent or other building blocks and the The bricks 9 arev applied to the outer surfaces of the translucent strips or plates, the said bricks being arranged in courses with broken joints as they would appear when they formed a wall of a building, with the proportionate spaces between them to simulate the joints as in a building. j

'lhe bricks 9 may be made of any material such as wood, burned clay, or the like, and they preferably have uneven surfaces, and those in one panel would have surtacecolorring dierent from that in another anel in order that the diderent e'ects pro uced by the use of a binder ormortar of a certain color might be studied. The fact that the bricks are relatively thick results in the production of a shadow between the courses of bricks similar to that resultin in a brick structure in which the joints etween the When the device is constructed in the manner indicated and a card is inserted back of lll@ the translucent plate, the coloI` of the card will be exhibited through the 'said plate at the joints, and the exposed color will represent the color of the mortar to be employed in abuilding in which the bricks are to be used and the :color scheme of the job Will 1. ln a masonry exhibitor, la plate, blocks.
